The Computational and Biological Vision Group, led by Hüseyin Boyacı and Katja Doerschner is part of Aysel Sabuncu Brain Research Center and National Magnetic Resonance Research Center (UMRAM), and operates jointly with the Department of Psychology and the Neuroscience Graduate ProgramBilkent University. Research in the lab is focused on visual perception and its neuronal underpinnings. We use behavioral experimentation, neuroimaging (fMRI), and computational modeling to find answers to problems of vision science.
